The MPQ8632GL-4-P Voltage Regulator is a DC-DC switching regulator from the PMIC (Power Management Integrated Circuit) family of voltage regulator devices. The MPQ8632GL-4-P operates from a 4.5V to 6.0V input voltage range, and provides an adjustable output voltage of 1.2V to 4.5V. It has an integrated MOSFET switch, thus optional external components are reduced. This makes the MPQ8632GL-4-P an ideal voltage regulator for space-constrained applicationsThe MPQ8632GL-4-P features a synchronous rectifying buck converter making it highly efficient and also helps with reducing switching noise. It has a maximum output current of 5A, with a switching frequency of up to 1MHz and a high conversion efficiency of up to 94%. The device also has a low quiescent current of 10µA and a high light load efficiency of up to 94%. For over-temperature protection, the device features an over-temperature and short Circuit protection (OTP) circuit, which shuts down the voltage regulator to stop further injury.The MPQ8632GL-4-P is best suited for applications which require a DC-DC voltage regulator with high efficiency, small package, and simple design. This device is ideal for mobile phones, digital cameras, portable media players, digital video recorders and other applications which require a power supply between 1.2V to 4.5V and need a highly efficient and low noise power solution.The MPQ8632GL-4-P device works on a principle of peak voltage control of the output. It has an internal error amplifier whose output is compared with the REF voltage present at the REF pin. Based on this comparison, the internal MOSFET switch is effectively turned on and off, thus regulating the output voltage.The MPQ8632GL-4-P also has an optional soft-start feature which helps to limit the inrush current as well as output ripple during Power On. The device has an operating temperature range of -40°C to +85°C, making it suitable for a wide range of applications.In summary, the MPQ8632GL-4-P is a DC-DC switching regulator from the PMIC family. It is best suited for applications which require a DC-DC voltage regulator with high efficiency, small package, and simple design. The device is ideal for applications which require power supply between 1.2V to 4.5V and need a highly efficient and low noise power solution. It has an integrated MOSFET switch, low quiescent current, high efficiency, and an adjustable output voltage.
